Scan and change file data content problem
Input file
Code:
>Read_1
XXXXXXXXXXSDFXXXXXDS  (condition 1: After the last "X" per line, if the distance is less than or equal to 3 letter, replace those not "X" letter with "X")
TREXXXXXXXSDFXXXXXDS (condition 2: Before the first "X" per line, if the distance is less than or equal to 3 letter, replace those not "X" letter with "X")
.
.

Desired output:
Code:
>Read_1
XXXXXXXXXXSDFXXXXXXX
XXXXXXXXXXSDFXXXXXXX
.
.

I got try using this one to solve the condition 1 problem. But it is not worked:
Code:
perl -pe 's/X[^X]{2}$/XXX/g' input

Thanks for any advice.
